This is a quick primer on analog signal processing, which lets you smooth out the noise from analog readings in Arduino microcontrollers, resolving one of the major disquiets of analog sensor inputs, very easily. Recently, […]
Feeding birds everyday will go a long way in the conservation of birds. So just remember that by installing a nest box in your garden you are actively participating in bringing about a vast change […]
The Arduino is an excellent microcontroller you probably already know that. An Arduino board can however only control low-current devices, so often you need a proper driver circuitry to handle the low-current control signals and […]
For a long time I’ve been wanting to use elegant spotlights in my workshop, and although I have a few issues to take care of, like a simple model and a way to install it, […]
On COVID-19 lockdown days, I came across several motor driver modules in my scrap box in the attic – surprisingly most of them are unused Chinese modules. The L293 Arduino Motor Driver Shield, in particular, […]
Hi there! Last week I finally managed to get an Arduino delivering a 16-bit PWM (pulse width modulation) output from a nifty piece of code. Is the experiment finished? Of course not. Anyway, in this […]
This article covers a simple version of my portable solar power box. In use, it worked flawlessly for me. Although this is a simple version, I am sure someone will be able to improve on […]
Building track lights and spotlights seems to be an obsession of mine. I built my first one in my school days or so, and this time my project thought is on simple power LED light […]
Sewing is a complex art that requires a lot of skill, precision, and patience. So, it’s critical to be able to see what’s doing, and a well-lit needle zone is very essential. Some high-end sewing […]
Using light is a common way to trap fish in fishery industry. Attracting fish by using artificial light source is to induce them to form a large shoal at night taking advantage of fish’s photo […]
